With regards to https://reviews.llvm.org/D53352: you can change the diff related to a patch whilst keeping discuccion and metadata of the diff.

Please add a generic description to the diff for an easy skimming on what you are accomplishing.

If I get this right, your tool will spit out a CPP file that is only include directives and perhaps the related conditional logic, or the final output of your tool is a file list? This is different than the `-M` flags in a way that it keeps conditions sane, rather than spitting out what includes were used if the input, with regards to the compiler options, was to be compiled?

Have you checked the tool //Include What You Use//? I'm curious in what way the mishappenings of that tool present themselves in yours. There were some challenges not overcome in a good way in IWYU, their readme goes into a bit more detail on this.
